Near Field Communication (NFC) allows contactless communication between devices like smartphones or tablets when they are within a few centimeters of each other. NFC uses radio signals to establish short-range wireless connections and can operate in either active or passive mode. Some common uses of NFC include mobile payments through services like Google Wallet, connecting devices via Bluetooth and Wi-Fi, social networking, and identifying documents. While NFC has a short range, combining it with other radio technologies can increase its applications.

3. WHAT IS NEAR FIELD
COMMUNICATION?
NFC is a form of contactless communication
between devices like smartphones or tablets.
 NFC is a short range high frequency wireless
communication technology.
 A radio communication is established by touching
the two phones or keeping them in a proximity of a
few centimeters.
 NFC is an extension of Radio frequency
identification or RFID technology.

4. HISTORY OF NFC

5. • In Active mode, both
devices with NFC
chip generates an
electromagnetic
field and exchange
data.

 Active mode
• In Passive mode,
there is only one
active device and
the other uses that
field to exchange
information.
 Passive mode
A NFC-enabled mobile
phone is paired with a
RFID-tagged "smart
poster"

10. CONCLUSION
Mobile handsets are the primary target for NFC
and soon NFC will be implemented in most
handheld devices. Even though NFC have the
shortest range among radio frequency
technologies, combining them with existing
technologies like Bluetooth can increase its range
of applications.
